Naturalism was depicted in the play by incorporating existing social conditions , language and through references to events , personalities and issues . This is evident in the backgrounds and demeanors of characters and in the manner of their interactions . Another factor that represents naturalist elements to the play is the use of developing sciences and issues into the story such as Stella 's nervous condition , Stanley 's involvement with the growing violence and vice of the city and Blanche 's rape and nervous breakdown . Another use of naturalism in the play is seen in the lack of dramatic role reversals among the characters and instead the characters are portrayed as individuals simply with lives that can go beyond their ability to control them.

Naturalism is depicted in many ways in the play. It begins with the description of Stella's house, located atop a dirty walk-up home, dogs barking, Jazz music in the distance, people yelling. Then you can feel it in Stanley's description as a dirty, oily man who is mostly like a gorilla, yelling about, hitting his wife, and being overall nasty towards Blanche. In the relationship between Stanley and Stella you see how sex makes a powerful binder and how even as she is pregnant and continues to get hit by him, it is the sex what keeps Stella forgiving her husband and ultimately betraying her sister.

But perhaps the most naturalist scene is Stanley's openly disclosing Blanche while she was drunk and weak, and then raping her. This is a significant depiction of the idea of naturalism because it brings human nature at its lowest point, and heightens its basic id, that is, the capability of evil and pain to others.
